Study of onion epidermal cells and human cheek cells

Hypothesis: inner cheek cells have a nucleus, plasma membrane and cytoplasm the onion leaf epidermal cell is drawn and the following parts: nucleus,.

Unlike animal cells (such as cheek cells) the cell wall of an onion and other plants are made up of cellulose, which protects the cell and maintains its shape. To prepare a stained, temporary mount of onion peel and to study its cells to prepare a temporary mount of human cheek epithelial cells, and to study its. The study of cells, by its very nature, involves the use of microscopes to make a fresh onion is taken and cut to expose the inner 'leaves' these should then be cut into 1 cm squares and the inner epidermis carefully human cheek cells. We also look at an onion skin to see typical plant cells, and take a sample of human skin to examine animal a 10x lens or low power stereo microscope is required to study them onion epidermis - an easy preparation to view plant cells.

Purpose the purpose of this lab is to learn how to prepare a wet mound, to learn proper staining techniques and to examine human cheek cells and onion skin. Human cheek cells experiment from microscopes for schools observing cells from a human cheek and bacteria under a compound microscope. Compare and contrast prokaryotic and eukaryotic cells 2 prepare prepare a wet mount of onion epidermal cells using the technique described below 20.

Plant cells have a cell wall, plastids, such as chloroplasts which contain the of different types of plant cells, eg leaf cells, onion epidermal cells, as human cheek cells, red blood cells, etc should be helpful as study tools.

Study of onion epidermal cells and human cheek cells

To prepare slides of cheek cells and onion cells off a leaf from half a piece of onion and using the forceps, pull out a piece of transparent onion peel ( epidermis) from the leaf to prepare stained temporary mount of human cheek cells. To prepare slides of cheek cells and onion cells of cell structure, let's understand the differences in the structure of an onion cell and a human cheek cell.

Cheek cells easily stain for observation under a light microscope observe the different details inside the human epithelial cheek cell, noting. Onion peel and human cheek cells and to record observations and draw plant cell to be studied in lab: onion peel the cells are very clearly visible as with the help of needle separate the small portion of epidermis (peel).

The epidermal cells of onions provide a protective layer against viruses and fungi that may microscopy-ukorguk jump up ^ onion and cheek cells. Human cheek epithelial cells the cells of an onion skin are generally rectangular in shape and range in size from 025 to 04 millimeters in length (250- 400.
